Get your taxes done using TurboTax

A week ago when I first prepared our taxes and again today, I am getting the message that our return contains forms that cannot be eFiled. As recommended, I looked up every form and schedule listed when I save my return in this tool - Intuit App - and they all say they are all supported. Why else can I not eFile my return? This is the first year using Home & Business instead of Deluxe and it is proving very frustrating!
